Description

Technical Field

[0001] The utility model relates to the technical field of building foundation structures, in particular to prefabricated assembled concrete building sprinklers. Background Art

[0002] Drainage refers to a drainage slope with a certain slope built with stone slabs or poured with concrete at the footing around the exterior walls of a house (on the outdoor floor). The function of the drainage is to quickly drain rainwater near the footing to prevent rainwater from eroding or seeping into the foundation, preventing the foundation from sinking, so as to ensure the solidity and durability of the house. With the rapid development of prefabricated buildings and the increasing maturity of various technologies, prefabricated components have also begun to be used in concrete drainage projects.

[0003] Traditional sprinklers all use cast-in-place sprinklers. After long-term use, cast-in-place sprinkler systems are prone to quality problems such as freezing, cracking, and sinking. At the same time, there will be gaps at the corners of the sprinklers, which will seep and sink after long-term use. Moreover, when problems arise with the sprinklers in the later stage and they need to be repaired, large areas of the sprinklers need to be removed and then re-poured, which will increase maintenance costs and waste more manpower. Utility Model Content

[0004] The purpose of the present invention is to provide a prefabricated assembled concrete building water dispersion device to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A prefabricated assembled concrete building sprinkler comprises a wall and a floor, wherein the wall is provided with a panel groove, the wall is provided with a first card slot connected to the panel groove, a wall panel is slidably arranged in the panel groove and the first card slot, the wall panel is provided with a second card slot near the first card slot, the wall panel is provided with a groove away from the second card slot, the wall panel is provided with a plurality of screw holes, and a sprinkler plate is movably arranged on the floor.

[0007] Preferably, the cross-section of the water spreading plate is trapezoidal, and a protrusion that can coincide with the groove is fixedly provided on the upper end of the water spreading plate, a spherical protrusion is fixedly provided on one side of the water spreading plate, and a spherical groove that can coincide with the spherical protrusion is provided on the other side, and a plurality of rotating holes are provided on the inclined surface of the water spreading plate, and an internal threaded sleeve is rotatably provided inside the rotating hole, and the internal threaded sleeve is threadedly engaged with an external threaded sleeve, and the external threaded sleeve is provided with a plurality of discharge holes.

[0008] Preferably, the portion of the wall panel at the second clamping slot that is clamped in the first clamping slot is higher than the portion of the wall panel outside the wall, and the portion of the wall panel outside the wall at the second clamping slot is an inclined surface.

[0009] Preferably, the spherical protrusion and the spherical groove are both higher on one side close to the protrusion than on the other side, and the top of the spherical protrusion must be higher than the connection with the water dispersion plate.

[0010] Preferably, a cross rod is fixedly provided in the internal threaded sleeve.

[0011] Preferably, there are at least four rotating holes and they are symmetrically distributed, the water diffuser is provided with a card slot three at the rotating hole, a card slot three is provided with a card cap, the water diffuser is provided with a drainage hole connected to the card slot three inside, and the side of the drainage hole away from the card slot three must be lower than the card slot three and higher than the spherical protrusion.

[0012] Preferably, there are at least two screw holes and they are symmetrically distributed.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. During the use of the utility model, the water-sprinkling board and the wall panel are prefabricated by a mold, and a panel groove and a card groove 1 are opened on the wall. Then, the spherical protrusion of one water-sprinkling board is inserted into the spherical groove of the other, the water-sprinkling board placed on the ground is spliced and leaned against the wall, and then the wall panel is placed on the water-sprinkling board and leaned against the wall, and the internal threaded sleeve is rotated to extend the external threaded sleeve, the water-sprinkling board is raised, and the wall panel is clamped into the card groove 1 and the panel groove, and then the expansion screw is used to fix it through the screw hole. The wall panel is fixed on the wall, and then concrete or foam glue is injected into the ground through the internal and external threaded sleeves to fill the gap between the sprinkling board and the ground, so as to support the sprinkling board. Since the part of the wall panel that is inserted into the slot is higher than the outer part of the wall, the water on the wall will flow into the sprinkling board, and the water on the sprinkling board will flow to the lower part of the sprinkling board, thus away from the corner of the wall. Even if a small amount of water will flow down from the gap between the two sprinkling boards, the spherical protrusions will block it, so that the water in the gap will also flow to the lower part of the sprinkling board away from the corner of the wall.

[0015] 2. During use, if the diffuser system has quality problems such as frost heave and cracking and needs to be replaced, you only need to remove the diffuser plate and wall panel with problems and replace them according to the installation steps. The operation is very convenient. If the diffuser system sinks in the later stage, you only need to rotate the internal threaded sleeve, extend the external threaded sleeve to the ground, raise the diffuser plate and wall panel, and then use the internal and external threaded sleeves to fill the gap between the diffuser plate and the ground to solve the sinking problem. The entire maintenance cost is very low and does not require too much manpower. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figures 1-6 , the utility model provides a technical solution:

[0025] Example 1:

[0026] The prefabricated assembled concrete building water dispersion comprises a wall 1 and a floor 2, characterized in that: the wall 1 is provided with a panel groove 3, a wall panel 5 can be placed in the panel groove 3, the wall 1 is provided with a card slot 4 connected to the panel groove 3, the card slot 4 can clamp the wall panel 5, the panel groove 3 and the card slot 4 are provided with a wall panel 5 slidingly, the wall panel 5 is provided with a card slot 2 6 near the card slot 1 4, and the wall panel 5 is provided with a groove 7 away from the card slot 2 6, the groove 7 is fitted with a protrusion 10 at the upper end of the water dispersion plate 9, and the height of the protrusion 10 is 1.5mm. The angle of the slot 1 is higher than the angle between the wall panel 5 and the diffuser 9, which can prevent water from flowing into the corner from the gap and causing the diffuser 9 to sink. The part of the wall panel 5 stuck in the slot 1 4 at the second slot 6 is higher than the part of the wall panel 5 outside the wall 1, which can prevent water flowing down from the wall 1 from entering the back of the wall panel 5 and then flowing into the corner. The part of the wall panel 5 outside the wall 1 at the second slot 6 is an inclined surface, which can quickly drain the water flowing down from the wall 1 to the diffuser 9, preventing it from accumulating in the gap between the wall 1 and the wall panel 5.

[0027] The wall panel 5 is provided with several screw holes 8. The diameter of the screw hole 8 on the side close to the wall 1 is smaller than the diameter on the side away from the wall 1, which can effectively prevent water flowing down the wall panel 5 from flowing into the back of the wall panel 5 through the screw holes 8. There are at least two screw holes 8 and they are symmetrically distributed. The wall panel 5 can be fixed to the wall 1 by using expansion screws to pass through the screw holes 8. A water dispersion plate 9 is movably provided on the ground 2.

[0028] Example 2:

[0029] The cross section of the water dispersion plate 9 is trapezoidal, and a protrusion 10 that can coincide with the groove 7 is fixedly provided on the upper end of the water dispersion plate 9. The upper surface of the water dispersion plate 9 is the same size as the lower surface of the wall panel 5 and can be merged. A spherical protrusion 11 is fixedly provided on one side of the water dispersion plate 9, and a spherical groove 12 that can coincide with the spherical protrusion 11 is provided on the other side. The spherical protrusion 11 on one water dispersion plate 9 can be inserted into the spherical groove 12 of another water dispersion plate 9. The spherical protrusion 11 and the spherical groove 12 are higher on one side close to the protrusion 10 than on the other side. The top of the spherical protrusion 11 must be higher than the connection with the water dispersion plate 9, which can prevent water from seeping into the gap between the two water dispersion plates 9 from flowing to the bottom of the water dispersion plate 9, but will flow to the lower part of the water dispersion plate 9 through the top of the connection between the spherical protrusion 11 and the water dispersion plate 9.

[0030] The inclined surface of the water-spreading plate 9 is provided with a plurality of rotating holes 13, and the rotating holes 13 are provided with at least four and symmetrically distributed. The water-spreading plate 9 is provided with a card slot 3 18 at the rotating hole 13, and a card cap 19 is provided on the card slot 3 18. The inside of the water-spreading plate 9 is provided with a drainage hole 20 connected to the card slot 3 18. The side of the drainage hole 20 away from the card slot 3 18 must be lower than the card slot 3 18 and higher than the spherical protrusion 11. The water on the inclined surface of the water-spreading plate 9 will flow into the card slot 3 18 from the gap between the card cap 19 and the water-spreading plate 9, and then will pass through the drainage hole 2 The water flows out from the card slot 3 18 and finally flows to the lower part of the water dispersion plate 9 through the upper part of the connection between the spherical protrusion 11 and the water dispersion plate 9. An internal threaded sleeve 14 is rotatably fixed inside the rotating hole 13. A cross rod 17 is fixed in the internal threaded sleeve 14. The internal threaded sleeve 14 is threadedly engaged with an external threaded sleeve 15. The external threaded sleeve 15 is provided with a plurality of discharge holes 16. Both the internal threaded sleeve 14 and the external threaded sleeve 15 are hollow structures. Concrete or foam can enter the lower part of the water dispersion plate 9 through the discharge holes 16 provided on the external threaded sleeve 15.

[0031] Working principle: First, the water-sprinkling plate 9 and the wall panel 5 are prefabricated by a mold, and then the panel groove 3 and the card groove 1 4 are opened on the wall 1. The spherical protrusion 11 on one water-sprinkling plate 9 is inserted into the spherical groove 12 on the other water-sprinkling plate 9, and the water-sprinkling plates 9 are spliced. Then the wall panel 5 is placed on the water-sprinkling plate 9 and leaned against the wall 1, so that the protrusion 10 on the water-sprinkling plate 9 fits with the groove 7 opened on the wall panel 5. The internal threaded sleeve 14 is rotated by the cross rod 17 to extend the external threaded sleeve 15, thereby lifting the water-sprinkling plate 9, and the wall panel 5 is lifted and carded into the card groove 1 4 and the panel groove 3, and then screwed. Expansion screws are used to fix the wall panel 5 to the wall 1 through the hole 8, and then concrete or foam is injected into the ground 2 through the discharge hole 16 opened by the external threaded sleeve 15 to fill the gap between the water dispersion plate 9 and the ground 2, and support the water dispersion plate 9. Since the part of the wall panel 5 that is inserted into the card slot 4 is higher than the outer part of the wall 1, the water on the wall 1 will flow into the water dispersion plate 9, and the water on the water dispersion plate 9 will flow to the lower part of the water dispersion plate 9, thereby staying away from the corner of the wall. Even if a small amount of water will flow down from the gap between the two water dispersion plates 9, the spherical protrusion 11 will block the water, so that the water in the gap will also flow to the lower part of the water dispersion plate 9 and thus stay away from the corner of the wall.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
